The abilities might be different too. Since Naruto has his own set of skills like the Rasengan and Sage Mode, his Susanoo could incorporate those elements. For example, his Susanoo's hands could form giant Rasengan - like attacks, or it could have the ability to enter Sage Mode, which would be a huge departure from the regular Uchiha Susanoo's abilities.
If Naruto saved the Uchiha clan, the story of the Hidden Leaf Village would be rewritten. The history of the Uchiha's massacre would no longer be a dark stain on the village's past. The Uchiha would contribute their unique skills and abilities to the village's development. For example, their Sharingan abilities could be used for better security or in battles against common enemies. There would also be a change in the relationships between characters. People who were once enemies of the Uchiha might have to learn to work with them.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
Often, the theme of friendship between Kakashi and an Uchiha character is seen. Despite the differences between Kakashi and the Uchiha, they form strong bonds in fanfics. Also, the exploration of the Sharingan, the Uchiha's special ability, in relation to Kakashi is a common theme. Maybe Kakashi is learning more about it or helping an Uchiha with its control.
One possible scenario could be that Sarada is initially in awe. Meeting the Uchiha clan, she might feel a strong sense of belonging. She could discover new jutsus that were unique to the clan and passed down through generations. This would not only enhance her skills but also give her a deeper understanding of her heritage.
Kakashi might be initially surprised. But then, he would probably use it as a teaching moment for Naruto. He could say something like 'Naruto, stealing is not the way of a ninja.' And then give him a punishment like extra training.
For other Uchiha clan members, they could start to view Naruto in different ways. At first, they might be skeptical of him, but as he shows his strength and loyalty to the clan, they could come to accept him. This could also lead to Naruto influencing the Uchiha clan's traditional views and values, causing some of the younger members to think more openly about the clan's future and its relationship with the outside world.
The village of Konoha would also be in turmoil. The Uchiha were an important part of the village. Their massacre by Naruto would create a huge rift among the villagers. Some might support Naruto, believing he had a good reason, while others would be horrified and demand justice. It could lead to a civil war within the village.
In many fanfics, Naruto might save the Uchiha clan by preventing the massacre. He could use his influence and friendship to change Itachi's mind. For example, if Naruto had known about the threat to the Uchiha clan earlier, he might have been able to talk to the village elders and find a peaceful solution. He could also have protected the Uchiha clan from outside threats that might have led to their downfall.
Power and its consequences is another theme. The Uchiha are known for their powerful Sharingan. Fanfics often explore what happens when an Uchiha gains too much power or misuses it. They also look at how the clan's power affects their relationships with other clans in the Naruto universe. In addition, the theme of family loyalty is prevalent. The Uchiha clan has a strong sense of family, and fanfics often depict characters' loyalty to their clan members and how they navigate when that loyalty is tested. This can be seen in stories where an Uchiha has to choose between the greater good and the well - being of their clan.
